Data transmission method in enterprise network

Abstract

The invention relates to the technical field of network data transmission, in particular to a data transmission method. According to the data transmission method, a data file source is isolated from a data exchange system to ensure that the data source is not accessed by anyone other than a system administrator; a one-off downloading token is used for downloading data, so that when a user does not have a data file using right, the user cannot acquire a data file through technical means even if the user knows an identifier of the data file; during logging, a second token is acquired and is bound with terminal information, a bound terminal can use the downloading token and the second token in a non-logging state to acquire complete data file contents in a breakpoint transmission mode, and the second token is updated after each request and the downloading token is abolished after the whole data file is acquired, so that a one-off data channel is achieved, and accordingly, the safety of data transmission is ensured.

Problems solved by technology

[0002] In the process of transmitting network data, the enterprise network generally has encryption and decryption processes and network conversion processes at the bottom of the network. In this network environment, the data transmission rate is unstable and often interrupted, and the internal data of the enterprise network usually needs to be limited The range of awareness must ensure its security, so the above two problems must be solved when transferring data within the enterprise network

[0003] There are many existing data transfer methods, such as FTP, mail system, shared directory, website resources, website programs, etc. For the needs of data transfer within the enterprise network, the traditional data transfer methods usually have the following problems: a) The data connection lacks security, and the method of directly placing resources on the website or file server cannot prevent illegal users from downloading, receiving and using; b) It is impossible to verify the availability of users, as long as users get the address, they can download data. The security of the data of the object cannot be guaranteed; c) The viewing and usage rights management of data files is complicated. Using FTP or shared directory methods, the permission setting operation is very time-consuming, and it is not suitable for a large number of this type of operations on the server

f) The transmission tool developed directly based on the TCP connection can ensure data security after reasonable control, but it is difficult to deploy in the scenario where multiple factories work together

g) Using the SSL mode to transmit large data is very inefficient, and the bottom layer of the enterprise network is usually equipped with hardware encryption devices, making SSL unnecessary.

h) Common data transfer methods usually do not have enough detailed audit records to know the status of data transfer
